Patented June 20, 1944 QDoIJn'LEf-ACTINGIy PLANER HEAD The present invention relates to a novel and improved double-acting planer-"head,v the same having more particular reference to a structure which is possessed of appreciable refinements and improvements such as serve :to romote more reliable and satisfactory results. y

As is well known, most planer-head constructions are such as to embody a single cutting-tool, said tool functioning in one direction only. As a result of research I have discovered that `there are also a limited number `ot' different types of` so-called double-acting planer-heads, the func,- tion of the latter being, obviously,l to perform somewhat continuously and alternately whether the bed ofztheY machineis moved forwardly or backwardly. The present invention relates to the latter type of head constructions. 1

My primary aim is, therefore to generally im f prove upon double-acting planer-head construc-k tions, this being done through the medium of an ingenious structural arrangement characterized by simplicity, durability andsuch1an arrange-V ment of parts as to achieve the;l desired aim in what is believed tov be a more adequate and practicable manner.

In reducing topractice the speciiic principles of my improved adaptation, I have'evolved and produced a carefullyplanned andi properly designed structure whereinjthe essential novelty resides in the coacting lfeatures, making` it'fpossible to have readyv access itc the insidev clappe block and .its tool retention: means..

Other features vand ladvantages will become more readily apparent from the following description and the accompanying illustrative drawings.

In the drawings, wherein like numerals are employed to designate like parts throughout the views- Figure 1 is a side elevational view of the duplex or double-acting planer-head constructed in accordance with the principles of the present invention.

Figure 2 is a similar View with parts in section and elevation to more readily disclose the specific construction and arrangement of said parts.

Figure 3 is an end elevation, that is, a view of Figure 1 observing the structure in the direction from right to left. i

Figure 4 is a vertical section on the plane of the line 4 4 of Figure 2, looking in the direction of the arrows.

Figure 5 is a perspective view of the special thelatter heldinplacebya bolt I5 threadedv the clamping bolts for the so'called inside clapper block and associatedtool. Y Y

t The work is denoted bythe numeral 6 and the depending head, above said work, by the' numeral 1. The U-'shaped attachment or casting B is 5 secured to the head 'I by a king-pin bolt 9.' The web or bight portion I0 of the. casting has a segmental'riser I2projecting above the 'parallel sidewalls I I,.said riser I2 being secured in place bythe flange or lip I3 of the clamping clip I4,

into azsocket in the main head 'I. vAdjacent the outerend of the walls I provide a heavy partition I6 which constitutes athrust element'. or

abutment for the clapper blocks I1 and I8.

.l Theftool'supporting clapperblocks I'I andjl are hingedly mounted onv opposite sides of the abutment I6 by way of hinge pins I9 and 20 lasv shown to advantage in Figure 2. It will be' noticed, in'thisconnection, that thepartition or abutment I6 is spaced inwardly of the outer ends of `said walls I.I,dening a sort of a pocket forI the outer clapper block .I'I.' The conventional cutting tool 2| is secured byvclats or clips' 22 and bolts 23 to the block I1.-"''1"hus, when the block` I'I isrm against the abutment or partition I6vthe tool 2| functions .in 'the direction of the arrow A as disclosed in Figure 1. On the other hand, when the'inside clapper block -I8 is resting rmly against the opposite side of the, abutment I6 the inside tool 24 functions against the' work 6 in the direction ofthe arrow B. In the latter arrangementthe tool 24-is heldin place `.by a similar clip `25 and'said clip is secured byl bolts 26 threaded into the cleats 25 as indicated at 21.

It will be observed that I provide four vertical slots 28 in the abutment partition. The central portion of each slot is enlarged and rounded as at 29 to accommodate the projecting head of the adjacent bolts 26. This serves to accommodate the cylindrical socket 30 of the wrench 3| shown in Figure 5. The wrench is provided with a suitable crank handle 32 tofacilitate its use.

As is obvious, in this improved head construc- 26 serve to retain the tool 24 in place by way of the cleats 25 have freedom of action in the acsocket wrench employed to tighten and Sen 55 commodation or adapter slots 28. This permits to be adjustedaboutahorizontal'axis;

Novelty is lpredi'cated'upon the adoptionv andv use of the U-shaped mount or casting 8, this adjustably mounted at 9 on the head 1, the adjust-l ment being had through the simple"dpstandingV segmental ilange I2 and associated clamping orv retention 4means I3, I4 and I5. .'l'hes'eimprove"-n ments in conjunction with the--doubleacting clapper blocks and tools constitute an important phase of my contribution to the art. portant, however, is the U-shaped mount' having the abutment partition. I6, there being clapper blocks hingedly mounte'dbetweenuthe side walls and said clapper blocks operating intermittently and being so constructed ,and associated, with the apertured partition as to achieve the desired aims. f v

Attention is directed to the fact that the design of this planer head is such thatthe latest and most modern planer. tools' can be used in con'- nection therewith. These toolsv measure lanywhere from one and one-half inchesin square stock-up to two and two and one-half inches stock. They also run from eight to sixteen inches in length. It isY feltl that this is an imp-- portant point tothe extent that the head is mod'- ern and up-to-date andl expressly designed to meet. conditions in commonpractice as of this date.

It is thought that'persons skilledin the artto which the invention relates-willV be ableJ to obtain blocks hingedly mounted between the side walls and located on opposite sides of said partition, and means for adjustably and detachably securing alternately operable tools to the respective clapper blocks.

2. In a double-acting planer-head construction of the class described, a body having an abutment partition, clapper blocks hingedly mounted on the body on opposite sides of the partitiomcIeats-and bolts for securing tools to the respective blocks', said partition having' apertures therein, and the bolts from one of said clapper y blocks projecting into said apertures in the man- ,-ner and for the purposes described.

" 3`. In a double-acting planer-head construction offtheiclass described, a U-shaped casting having meansjior adjustably and detachably mounting MO'reeinif i j same on a supporting and operating head, a transverse partition between the outer end portions ,of the side walls of said casting, said partition being provided with a plurality of vertically a clearunderstanding` of the inventionafter conment of detailsV coming within the eld of inveny tion claimed ma'yresorted to in actual practice, if

desired.

Having described the invention, what `is claimed as new is: if
